IMPROVEMENT IN SHlNGLE-MACHINES.

The Schedule referred to in these Lettere Patent and making part of thesame.

To all 'whom it may concern:

` Be it known that I, JOSEPH JIMO, of Vergennes, in the: county ofAddison and State of Vermont, have invented certain .Improvements inShingle-Machine, of which the following is a specification, referencebeing had to the accompanying drawing.

My invention relates to that class of shinglemachines in which the boltsor blocks are fed against the saw by a horizontal rotating table; and

The invention consists in an improved manner of constructing andarranging various details, as hereinafter described. l

' Figure l is a top plan view of the machine with certain portionsbroken away;

Figure 2 is a side elevationV of the same;

1Figure 3 is auend View otL the tilting table and the shaft foroperating it; and

Figure 4, an end view of the planer or cutter.

A represents the frame ofthe machine, at thecenter of which is mounted avertical shaft, B, having on its upper end a large circular horizontaltable, O, and' on its lower end a cog-wheel, at.

By the side of shaft B is mounted another vertical shaft, D, providedwith cone-pulleys b and a-pinion, c, which gears into wheel a, as shownin figs. l and 2.

In one corner of the frame isV mounted a vertical shaft, E, providedwith a large pulley, c, and conel pulleys f, the latter being connectedby a crossed belt,

g, with pulleys b, as shown in iig. 2;

At the middle of the frame, near one side, is mounted a vertical shaft,F, provided with three fixed pulleys, h, i, and j, and also on its upperend, above the frame, with a circular saw, G.

The pulley h, which is the smallest of the three, is connected, by abelt, 7:, with the large pulley -e of the corner-shaft E, as shown inlig. 1 and the pulley i is connected, by a belt, l, with a large pulley,m, on a vertical driving-shaft, H, mounted in one corner of the frame,as shown' in iig. l.

The shaft H is also provided with a second pulley, n, through which thepower to drive the` machine is applied.

When the shaft H is set in operation motion is transmitted through beltl to the saw-shaft, and thence through belts h and g to the pinion c,which in turn rotates the wheel a and turns the table or hed C.

Owing to the arrangement and proportion of the various parts the saw isrevolved at a high and the 1 bed at a slow rate of speed.

Through the bed (l is formed a number of rectangular openings, J, toreceive the bolts or blocks of, wood, so that as the. bed revolves thedifferent bolts will be carried in succession over the saw G.

To the bed C, at each opening J, is pivoted a pair of levers, K L, oneat each end ofthe opening. The

inner ends of the levers, opposite the openings J, are provided withteeth to engage in and hold the block or bolt ofV wood. y

The two levers are connected by a bar or link, fr, in the manner shown,so that they shall both swing against or away from the block at the sametime.

The end of lever K of each pair is extended out beyond the edge ofthebed C, and an upright, M, is secured to the side ot' the main frame insuch manner as to strike against levers K as thebed revolves, and thusopen-the different pairs of arms in succession.

A spring, c, is secured behind each arm K, so as to keep the pairclosed, except for the instant they are held open in passing standard M.

At one side of frame A, under the bed C, is mounted a tilting bed ortable, N, shown in place in ligs. 1 and 2, and detached in Iig. 3.

This table is support-ed at one side on a stationary horizontal shaft,Izo, and at the opposite side it rests on a rotating shaft, x, iiattenedon its two sides, so that when the table rests on either of the flatsides of the shaft it stands ,inclined in one direction; but when theshaft is turned up edgewise the bed is inclined in the oppositedirection.

To the outer end of shaft :c is secured a toothed wheel, O, and to theouter edge of the bed, close together, are secured three teeth orfingers, y, which, as the bed C revolves, engage with the. wheel O andturn the same, the shaft being turned a quarter of a revolution at eachrevolution ofthe bed.

During one revolution of the bed C the table N' turn wheel O and tiltthe table in the opposite direction. The table-remains iu thislatterpositiou until the bed completes the second revolution, when thelingers again come into play and the table is tilted back in the firstposition, and so on repeatedly.

On the opposite side of the framefrom the saw, under the bed C, ismounted a horizontal shaft, P, provided with cutting or planing-blades,as shown in figs. 1, 2, and 3.

On the outer end of this shaft P is secured a pulley, lt, and to theframe below said pulley aie secured two guide-pulleys, S, as shown.

A belt, T, is passed over the pulley 1t and under the pulleys S, andthen crossed and carried around pulley- 7' of shaft F, as shown in gs. land 2.

The various parts being thus arranged, a bolt clamped in cach of theopenings J, and the machine set in motion, the operation is as follows:

As the bed C revolves each bolt is carried around over the rotary cutterP and the underside ofthe bolt smoothed or planed off. The bolt thenpasses around until it is over the table N, when the lever K strikesstandard andlthe levers are opened tir zuifiiistaut so asto let the boltdrop down `and rest on the table N. I

As soon as lever K passes the standard the levers clasp the block andhold it in position while it is carried around yover the saw, which cutsa shingle loft" from the under side. l

The block is then carried around as before, being first planed off', andthen released so as to rest on the table; then clamped again, and nallypresented Vtothensaw. y Y n The table N is placed below the level of thesaw, and serves as a gauge to regulate the thickness of the shingle.

Owing to the arrangement of the Atable N,vwhieh v stands at oneinclination during one revolution ofthe bed 0, and at the oppositeinclination during the next revolution, the saw outs obliquely throughthe boltfirst in one direction and then in the other, so that therev isno Waste of material, as the butt of one.shingle is taken o" from theright and the next o" from the left end ofthe bolt. To provide forstopping the motion of the bed without stopping the other parts, thelower end of shaft D is mounted in 'a box, z, arranged to slidelaterally,

and a lever, ax, is pivoted 'to the frame and connected at its inner endwith the sliding box, and at its outer end with a vertical pivotedhand-lever, S, as shown. By moving the hand-lever the box z and thelower end of shaft D maybe moved so as to throw the pin ion c in and outof gear, and thus the bed'stopped and started when desired.

Having thus described my invention,

What I claim is- 1. lhe tilting table N and the shaft' having the wheelO attached, in combination with the rotating ltable C provided with thefingers '1, all constructed and arranged to operate as' set forth.

2. A shingle-machine, .consisting of the rotating table' G with its dogsK L, the saw G, .the tilting table N, and revolving planer P, allconstructed and arranged to operate substantially as herein shown anddescribed.

JOSEPH JIMO.
